@z4o4z example code，thanks `

        dataSource  : [],
        isRefreshing: false,

        isHeaderFixed: false,
    }
    this.dataUrl = "#"
    this.page=1
    this.rows=[]
}

componentDidMount() {
    this.onFetch()
}

onFetch = () => {
    Net.get(this.dataUrl, {num: 5, cid: 1, page: this.page}).then(ret => {

        if(this.state.dataSource.length==0){
            this.rows=ret.data
        }else{
            this.rows=this.rows.concat(ret.data)
        }
        this.setState({

Hi @yunuo-tech, sorry for the long response. You right it is a bug. But I have a good news, it's already fixed in the v1.5.2. Can you test the new version?
